Welcome Decker!

It's nice to see you here.
I would suggest something more obtainable to more players. Giving away a car only goes to one player and there is room for discouragement. Since you are dealing with decks, some nice custom playing cards could be sent out. Players love gifts in the mail! Along with some good old fashioned cash prizes with a large cash incentive for top prize. I'm not sure how cash prizes work from an affilate manager perspective. I don't see many of those.
Wishing you much success Decker.
